Hi,
Firstly the database can be moved without loss of information, please refer to this document
How to move/copy/backup the points database
If you have an iPad or an iPhone you need to purchase the app on the app store, you only need to buy it once if you have two devices on the same app store account, once installed refer to the document above for moving your database onto the device.

All the best
